A straightforward locking cat door for exterior use as long as your door thickness falls within its 0.25 to 1.5 inch range and your pet is under 22 pounds.
A tightly specified add-on flap for patio screens, right for small pets within its measured opening but not a fit if your screen frame runs thicker than half an inch.

A microchip-activated cat flap that reads ISO and AVID chips and manages access for up to 30 pets, best suited to owners who have already confirmed their door or wall thickness.
